j This invention-relates to cabinetsand has special reference to pressed metal cabinets. ltiore particularly the invention relates to a corner construction for pressed steel cabinets.

In the manufacture of cabinets of this class 'it isusual .to form the body of the cabinet of one sheet of metal cut and folded to the shape of-a box havingone side open. The edge of thisopen side is provided with an outwardly extending flange; and to this flange is secured, preferably by spotwelding,-a flange formedon the inner leg'of a U-shaped rim member. H form thisrim member flange by pressing the It is desirable to metalto shape so that no crack will be formed at the corner and the cabinet door will it smoothly therein Experience hasleg of such a U-shaped rim member because the edges of a cut under these conditions rim may be pressed to U-shape and yet the move apart during the bending.

The principal obfect of the present invention is to provide an improved construct-ion of such a'corner wherein the metal of the corner present a smooth surface on the face against which the door or cover fits.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel cletails of construction and combinations of parts. hereinafter fully described, illustrated in the accompanying drawings and specifically claimed V In the accompanying drawings like characters of reference indicate like parts in the several views, and:

The rim member is formed from a blank,:

one corner of which is shown in Figure 4 and it will be notedthat this rim member is provided with a face p0rtioni13 and outer wall portions 14: defined from the face por- V tion by the fold lines 15. These lines are continued through each other at the corner, the continuation of one line being by a fold line 16 and the continuation of the other line being by a slit 1'? so that a corner piece 18 1s provided. Each wall portion l4 has a flange 19 Xtending along the edge opposite Y the face portion and defined from the wall by a fold line 20. In the formation of this part of the rim the portions 141: are bent to lie perpendicularly to the face 13 and the corner 18 is lapped over the outside ofoneportion 14; Also the flanges 19 are-bent in as shownin Figure 5. V

The inner wall is formed bycutting'a slit.

'21 in from the re-entrant angle of the blank to the junction of fold lines 22 which define 24 are formed on these inner walls, being defined by fold lines 25. These inner wallsare bentperpendicularly to the face 13 and the flanges 24 are, bent inwardly as shownv in the inner walls 23 from the face 13. Flanges Figure 5 so that they fit beneath the flanges T 11 of the body and may there be secured as by spot welding. When thus bent the inner corner of the. rim is provided at the. side wall with a V-shaped gap 26. which is filled by' the filler piece. This filler. piece consists of a strip of metal having legs 27 extending at right angles and the angular portion of 110 the filler piece is pressed inwardly along diagonal lines-28 to a displacement equal to thethickness of themetal of the rim, the
